UNITED STATES PATENT CFFIGE- A. DE LANDSEE, OF PARIS, FRANCE.

HVDROCARBON-BURNER.

Specification forming part of Letters Patent No. [00,268, dated March 1,1870.

To all whom it may concern.-

Be it known that I, ADOLPHE DE LANDsEE, civil engineer, of 13 rueGaillon, Paris, France, have invented certain new and usefulImprovements in Grates for Burning Liquid Fuel; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon.

My invention has reference to a particular construction and form ofgrate, to which the liquid fuel is fed in a continuous stream, or dropby drop, from a reservoir situated in any convenient place.

My apparatus, when applied to a steamboiler, is placed over an openingcorresponding in place to the ordinary fire-door, and is composed of twomain parts divided by a horizontal line, the upper one of which ispermanently attached to the front of furnace or boiler, as the case maybe, while the lower half or door is fixed to the same by means of avertical hinge, enabling it to be readily opened and closed. In thislower half 1 form two apertures, the upper one of which is terminated bya shallow trough, into which the liquid fuel is fed, and which servesalso for the passage of air, while the lower one consists in a series ofsmall holes serving to direct a second current of air on the flameissuing trom the upper aperture toward the boiler.

In the accompanying drawing, Figure 1 is a front elevation ofone ofmycom plete apparatus; Fig. 2, a sectional plan of same through A A, Figs.1 and 3; and Fig. 3, a vertical section of same taken through B B, Figs.1 and 2.

a is the front of furnace or boiler, to which my apparatus is attached.

b is the upper half and c the lower half of my said apparatus, theformer of which is permanently attached to a by the bolts d d d, whilethe latter is fitted to and swings on the hinge-pin 0, carried in thepart f, which is attached to the face a by the bolts 9 g.

These two halves are constructed so as to unite at the line 1 2, Fig. 3,and when united they form the inclined passage h h, the lower half ofwhich contains the trough i.

The liquid fluid is admitted into the trough by the vertical pipe j andhorizontal nozzles k is Is, united to said half a by brass pipes andunion joints l.

The supply of liquid to the trough is regulated so as never to overflowthe lip m. Thus a clear space, an n, is always reserved for the passageof the intermingled gases and air.

In order to regulate said space I make use of the sliding plate 0,raised or lowered by the nutp and set in place by the nuts q g. Thisplate 0 also serves to protect the castiron' mouth-piece from theeffects of intense heat, and is itself easily replaced when injured bythe heat.

The lower half or door 0 also contains, as above stated, the aperturesby means of which a second current of air is injected on the flames.These apertures consist in one or several rows of holes, 1 r, l igs.2and 3,1eading from the common external passage 3.

In order to regulate the amount of air admitted both above and below theflame, independently of the means indicated with respect to plate 0, aswell as to interrupt at any time approximately all passage of air to thegrate, I make use of sliding doors t u, adapted externally at theorifices ot'said passages.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The particular construction ot'upper half I) of said-grate, with itssliding and regulating plate 0 and accessory parts.

2. The particular construction of lower half or door a, with its trough'0 supply-pipejk, and accessory parts, all attached to said door 0.

3. The method of feeding air by two separate currents, one above and theother below the flame of burning liquid, substantially as specified.
